oil leak!

**crossback** · March 3rd, 2004 12:25 AM

guys,

last year i had my timing belt replaced! for the past months i didnt noticed any unusual from my engine bay, not until recently, where there appears to be some kind of oil leaking from the top of my piston ring case (where the spark plugs and HT wires are) its leaking from the four bolts that locks the pistong ring case (?)....

i went to Servitek in west ave to have it check.... they just put some kind of a sealant in it (orange ang kulay).... but it lasted only for 2 days... balik na naman yung tagas!

you think i should replaced the bolts... sabi kasi sa servitek.... the bolts daw are assembly, di kaw pwede yung gasket lang palitan....

pleas help... baka kaya ko pa i-diy!

txs

I'm not really sure where that piston ring case is located. All I know is, parts from top part are valve cover, cylinder head, cylinder head gasket then engine block.

Common remedy for leaks are high-temp sealants, but most color I've seen and used is colored red. Kung sa valve cover may tagas, usual 8 bolt pattern yan.

Baka naman kulang sa torque ang pagkakahigpit ng servitek? Ano ba car mo?

Sir ungas, censya na i'm a total moron when it comes to engine terms... malamang VALVE COVER siguro tawag dun... yun yung binuksan nung nag palit ako ng timing belt, pag bukas kita mo yung langis...

Anu ba yung 8-bolt pattern.... (sori... engot talaga ko pagdating sa kotse)... Kung yun dapat gawin, bat di kaya sinugest ng servitek?

Sir Delta, Honda Vtec po ride ko....

txs ulit

Don't worry ganyan din naman kami dati, hehehe. :D

Primary culprit would have to be oil seals, iba pa po ang timing belt cover sa engine valve cover. But in your case, when you opened it and has oil in it, this will probably your engine valve cover. Timing belt side of engines should be dry and free from any dirt, debris and oil. Sealant will not work on moving parts of your engine. But then again maybe some bolt retorque will save you more.

Crossback, common ata sa Civic iyan pag binuksan ang valve cover (yung takip sa ibabaw na may VTEC) pag binalik e di maganda ang pagkakasalpak, kaya may langis na tumatagas sa gilid niya, maski na tama ang paghigpit ng mekaniko.

Ang suggestion ko ay tanggalin mo na lang ulit yung valve cover (kelangan malamig makina), tapos lagyan mo ng high-temp sealant (color red) yung buong valve cover gasket (rubber ito sa ilalim nung valve cover). Pag ibabalik mo na ito, kailangan tama ang paghigpit, at may sequence sa paghigpit kelangan pag natapos mo yung isang bolt yung next bolt na hihigpitan mo ay yung nasa opposite na side.

Kung hindi naman malakas ang tagas (namamawis lang at hindi naman tumutulo sa sahig), pwede mo nang pabayaan muna yan.

Are you sure na hindi overfilled ang oil pan mo?

I don't know about Honda gaskets. Sa Kia kasi Php 120.00 lang ang OEM valve cover gasket. Napabili tuloy ako ng dalawa. hehehehe.

And do not overtorque the bolts (huwag sobrang higpit). Maganda sana kung may torque wrench ka para sukat na sukat ang higpit.

sir mgam natumbok mo! yun nga yun! yung cover na may "vtec" sa ibabaw!

boss otep, d naman - tama lang sa may max button ng dipstick ko yung oil level.....

anyway, balik ko nalang siguro ulit sa talyer pahigpitan ko and then kung ayaw parin, try ko na palit ng gasket/oil seal... sana mura lang din... (patay na naman bulsa ko nito) tsk tsk.

txs to all!

Just remind the mechanic not to overtighten.

If you 'squish' the gasket too much. Sira na iyan.

rule of thumb:

when something has a rubber gasket, there is no need to add a lot of silicone sealant to it. (i.e the valvecover/oilpan/etc). kung tama yung gamit na gasket this should be able to seal by itself without the help of sealant pa.

crossback, feel free to pass by the shop to have that replaced. once matigas na yung valvecover dapat di na lagyan ng sealant yan and palitan na sya agad ng gasket. also, be sure to have them clean the valve cover well para walang remnants ng old gasket which will cause the new one to seal improperly .
